Conse' quently themagnetic core of the Gramme like ring is magnetized and the armature sof the receiver caused to assume the position of strongest magneticeffect, which is that corresponding with the position of thetransmitting arm *3.

It will be readily appreciable that with the use of sufficientlypowerful currents transmitted through the conductors to the armature sof the receiver maybe caused to exert considerable power, therebyrendering it possible to utilize said armature either in the directapplication of power to a rudder of a vessel or to the control ofmechanism of any nat re desired by the user.

"10 not limit myself to the special form of apparatus herein shown anddescribed as I believe it is broadly new with me to transmit electricalenergy through a series of electrical conductors to a receiver whichwill impart to its moving part a motion always corresponding to themoving part of the transmitterand my claim is generic in thisparticular.

Having thus describ 1d my invention, what I claim, and desire to secureby Letters Pat ent of the United States, is

The combination of a transmitter containing a circularly arranged seriesof contact plates and a pair of contact brushes and contact ringsadapted to connect the said contact plates in pairs with the poles of asource of electricity, with a receiver containing a circularly arrangedseries of coils connected with each other and adapted to produce arelative angular motion between itself and a diametrically arrangedarmature, and a group of conductors equal in numberto the contactplates, each conductor connecting one of the said contact plates of thetransmitter with one of the junctions between consecutive coils of thereceiver, the whole being adapted to operate substantially as describedand for the purposes set forth.

In testimony whereof I have hereunto subscribed my name this 18th day ofJanuary, 1893.

AUGUST UTZINGER.
